ˌMae ˈWest noun [countable]
a humorous name for a type of life jacket (=an air-filled piece of clothing that you wear to stop yourself sinking in water) that was worn in World War II by people in the air force. It was given this name because its shape reminded people of the film actress Mae West, who was known for her large breasts.
